Serial streams with EOL defined as CR only.

[Daniel Jankins]

Hi,

I have a serial port that is streaming data.  The data is terminated by a /r only.

I am trying to use scanner.Scan () to break up the lines.  Is there a way to change the scanner end of line character to /r only?

Thank you

config := &serial.Config {
Name:        lmt.ComPort,
Baud:        57600,
ReadTimeout: 30 * time.Second,
Size:        8,
}

stream, err = serial.OpenPort(config)
if err != nil {
fmt.Printf("ERROR - Can not open com port:%s\n", lmt.ComPort)
return
}

scanner := bufio.NewScanner(stream)

for scanner.Scan() {
bufStr := scanner.Text()
.
.
.
}

See https://pkg.go.dev/bufio#Scanner.Split to change how the scanner
collects tokens.
